ATTACHMENT FOR SUGKER RODS.

rlhis inventiony relates to an attachment for use in connection withsucker rods of oil wells or the like, the primary object of theinvention being' to provide means or preventing rotary movement of thesucker rod, thereby insuring against the sucker rod sections becomingdisconnected.

A 'further object ot the invention is to provide means to insure theworking valve cups of the well seating in one position at all times,thereby equalizing the wear on the cups.

Another object of the invention is to provide a device ot this characterwhich may be readily and easily secured in the usual well construction,without making extensive alterations to install the attachment.

lWith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement ot parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing:

Figure 1 is a longitudinal sectional view through well tubing,illustrating the application or" the invention.

Figure 2 is a sectional view through the sucker rod attachement.

Figure 3 is a side elevational view thereof.

Figure l is a tranverse sectional `view through the attachment.

Figure 5 is a sectional view taken on line 5 5 ot Figure 1.

Figure 6 is a sectional view taken on line 6 6 of Figure 1.

Referring to the drawing in detail, the reterence character 5 designatesone end of the pump barrel which is threaded to receive the threadedextremity 6 ot the barrel or attachment, which is indicated generally bythe reference character 7.

The upper end ot the barrel 7 is threaded to connect with the irst jointof the well tubing, the well tubing being indicated by the referencecharacter 8. Formed in the inner surface of the barrel 7, and disposedopposite to each other, are grooves 9 which grooves are of lengths equalto the length of the strokel of the sucker rod, and are of widths toaccommodate the guiding blades 10 of the attachment, the grooves actingas guideways for the 1lades. The endsot these grooves are slightlyinclined as at 11 so that they device may be withdrawn should it bedesired to make repairs, or disassemble the sucker rod.

Forming an important part of the attachment is a body portion 12 havinga threaded extension 13 to be fitted in the threaded end of the suckerrod section 14, while at the upper end of the body portion 12 is athreaded bore to accommodate the threaded extremity 15 of the sucker rodsection 16.

Cut out portions are formed in the sides oit the body portion 12 andaccommodate the blades 10 that are held against displacement by means ofthe pins 1S that move in elongated openings 19 there being provided acoiled spring 2O fitted in an opening of the body portion 12, the endsof the coiled spring being seated in openings ot the blades 10.

Thus it will be obvious that movement of the blades 10 with respect tothe body portion 12, will be pernnttedy at all times, the action ot thespring 2O being such as to normally urge the blades into closeengagement with the walls of the grooves.

As the sucker rod is reciprocated vertically While in operation, it willbe seen that `all rotary movement of the sucker rod is prevented to theend that the possibilities of the sections of the sucker rod becomingdisconnected are eliminated.

I claim:

1. 1n combination with the well tubing and sucker rod ot a pump, abarrel secured between sections of the tubing and having grooves forme-dtherein, a body portion secured between sections of the sticker rod,movable blades supported by the body portion and movable in the grooves,and means for normally urging the blades laterally.

2. ln combination with the well tubing and sucker rod of a pump, anattachment including` a barrel secured between sections of the welltubing, said barrel having grooves, a

body portion secured between sections of they sucker rod, and resilientmembers extending trom thebody portion and movable in the grooves toguide the sucker rod while in operation.

3. In combination with the well tubing and sucker rod of a pump, anattachmentincluding a barrel secured between sections of the welltubing, a body portion secured between Well tubing, said barrel having,`grooves, a

body portion secured between sections of the sucker rod, said bodyportion having lateral cut out portions, spring pressed blades Withinthe out out portions, said blades being positioned in the grooves toguide the body portion and sucker rod to which the body portion isconnected.

5. In combination with the Well tubing and ksucker rod of a pump, abarrel positioned between sections of the Well tubing, a body portionseeuredbetyveen sections of the sucker rod, t and operating Within thebarrel, said barrel baving'grooves, and laterally extended members onthe body portion and operating in the grooves to prevent rotarymovernent of the suck-er rod. t

In testimony that I clairn tbe foregoing as my own, I have hereto aixedmy signature.
